• 1^st Question "What are the stages?"
  • ⋯  
• 1^st Response "Online Quiz"
  • ⋯   is held during Brain Awareness Week. Students study the book Neuroscience: Science of the
    Brain. An Introduction for Young Students by The British Neuroscience Association (BNA) and
    European Dana Alliance for the Brain (EDAB). They then complete an on-line quiz in their
    schools under exam conditions to determine their knowledge and understanding of the
    structure and function of the brain 14 - 20 March 2016
• 1^st Question "What to study?"
  • ⋯  
• 1^st Response "Electronic Book"
• 1^st Question "Contents"
  • ⋯  
• 3^rd Response "Chemical Messengers"
• 1^st Question "What happens after axon"
  • ⋯   Action potentials are transmitted along axons to
    specialised regions called synapses, where the axons
    contact the dendrites of other neurons. These consist of
    a presynaptic nerve ending, separated by a small gap from
    the postsynaptic component which is often located on a
    dendritic spine. The electrical currents responsible for the
    propagation of the action potential along axons cannot
    bridge the synaptic gap. Transmission across this gap is
    accomplished by chemical messengers called
    neurotransmitters
• 2^nd Response "Action Potential releases Ca++ that releases Enzymes"
  • ⋯  
• 1^st Question "What is the process?"
  • ⋯  
• Step (6 of 10):  "The neurotransmitters simulate RECEPTORs in the dendrites"
  • ⋯  
• 2^nd Question "How do the work?"
  • ⋯  
• 1^st Response "Timing and threshold"
